[Influence of the compensation of the geomagnetic field on human cognitive processes].
The influence of the compensation of the geomagnetic field to a level less than 0.4 microT on human cognitive processes has been studied. Forty persons took part in the study; they were divided by sex and age into four groups. The cognitive abilities of the persons were tested. Each person took part in two experiments: in control conditions and under the exposure to zero magnetic field. A 45-min exposure to zero magnetic field caused statistically significant changes in five of eight parameters of the cognitive tests. The magnitude of the effects varied between 1.3 and 6.2%, with an average value for all tests being 2.1% (p < 0.002, MANOVA). Exposure to zero magnetic field led predominantly to an increase in the number of errors and the time the task was performed as compared with the controls. Men passed the tests in zero magnetic field better than women, and young people did it better than aged persons. Groups of persons were distinguished that responded differently to zero magnetic field, the differences being not related to the age or gender.
